One-dimensional linear equation is a basic concept in mathematics and a key tool to solve many practical problems. The following is a handwritten newspaper about the linear equation of one variable for your reference:
First, the definition of one-dimensional linear equation
A linear equation with one variable is an equation, which contains an unknown number and a constant, and the degree of the unknown number is 1. The general form of this equation is ax+b=0 (where a and b are constants and a≠0).
Second, the solution of one-dimensional linear equation
The basic steps to solve the one-dimensional linear equation are: removing the denominator, brackets and shift terms, merging similar terms and converting them into 1. These steps are the basic methods to solve linear equations with one variable, and they are also effective tools to solve practical problems. For example, to solve the equation 2x+3=5, we can follow the following steps:
Denominator: Since the coefficients on both sides of the equation are integers, we can remove the denominator and get 2x+3=5. Remove brackets: Remove brackets on both sides of the equation to get 2x=2. Shift term: shift the constant terms on both sides of the equation to the other side of the equation to get 2x=2-3. Merge similar terms: Merge similar terms on both sides of the equation to get 2x=- 1. The coefficient is 1: both sides of the equation are divided by 2 at the same time to get x=- 1/2.
Third, the application of one-dimensional linear equation
One-dimensional linear equation is an important tool to solve many practical problems. For example, calculate discounts, calculate interest rates, and solve travel problems. Shopping can be solved by a linear equation at any time. Mastering the solution of linear equation with one variable can help us solve practical problems in life better.
In a word, linear equation is a basic concept in mathematics and an important tool to solve many practical problems. By learning and mastering the solution of linear equation of one variable, we can better solve practical problems in life.
